I think you drastically overestimate the military importance of nuclear weapons.
Since I fucked up the math in channel, which drove me to spend half hour poring over the details to make sure everything's correct, I hurry to save the results here.
-
I. World Uranium reserves stand ati about about 6*10^9 kgs. Just about 0.72% of this is usable for the purpose. Uranium molar mass is ~250 [grams/mol] which means ~ 6*10^9 * 1000/250 * 6*10^23 atoms in total.
II. Energy output is ~200 MeV per fission event. The total ideally available energy is thus 6*109 * 0.0072 * 1000 / 250 * 6*1023 * 200 * 106 = ~2 * 10^40 eV.
III. Land surface is ~1.50 * 1014 square meters, so on average there's a total of ~1.3 * 1026 eV available per square meter, ~21 or so MJoules. This means that if there's water on the floorii, eight or so milimeters high, all-out nuclear war will dry it off.iii Guess what, the Sun does the same in an afternoon.iv Big whoop.
This, of course, provided you manage to mine all the uranium there isv, and manage to fission it in such a way that no atom escapes your wrath, and further provided that the sea is magically off limits to the enemy.vi
Consider also the problem of costs.
-
For one thing, the US total current arsenal is around 547 "megatonnes"vii, worth 4.1 PJoules or 2.6 * 10 31 eV each. Therefore the entire US atomic armaments (all 1.4 * 1034 eV's worth of it) come to almost 0.0001% of what's contemplated here. Provided, of course, they even work.
For the other thing, a single Trident missile (which is, as alf well points out, not at all the whole story) costs 30 to 40 million dollars, and delivers 15-20 TeraJoules, ideally. The delivery costs of fissile material involved in the Operation Dry Bathroom Floors would alone count for something like... 4 to 5 trillion dollars.viii The 2015 US budget is in total a shade under 4 trillion, so it wouldn't cover delivery. To get an idea of what this means : the US couldn't afford to pay for the taxi. Not the show, not the dinner, and definitely not the girl. Just... the taxi.
tl;dr Contrary to what is generally propagandized, there isn't a way to use nuclear weapons effectually on the field. The only effectual use for them is in mass media, for propaganda purposes. That's it.
———- It is important to note that Uranium is pretty much only found in the crust, and because it is principally an alpha emitter it is perhaps naive to imagine large deposits await unknown. Certainly much more naive than the same expectation about fossil fuel reserves, and last I checked that's not commonly held. [↩]
- Room temperature water costs about 2.6MJ per liter to dry off, and a liter of water stands a milimeter tall on a square meter surface. [↩]
- We're making the generous assumption that all that energy can in fact be transferred. This is ludicrous, of course. [↩]
- The Earth receives something to the tune of 200 PetaWatts from the Sun, and if the afternoon is four hours long this comes down to 2.88 * 1021 Joules, or 1.8 * 1040 eV. Same deal. [↩]
- Mostly in Australia. [↩]
- Which it very much isn't. In fact atomic submarines are by far the most hardy elements in case of nuclear war. [↩]
- Pro-tip : whenever someone's using some sort of "special" unit for banal stuff, it's because they're trying to scam you. [↩]
- Provided of course the supply of these things is absolutely elastic, and you can buy ten million for the same price you paid for one.
Actually, strike that : provided of course the US can even produce anything whatsoever anymore. I seem to recall a pellet of a billion or so dollars "lost" in Iraq, I seem to recall last the Pentagon humbly proposed to audit Blackwater the Grand Master of that wholly sovereign Templar order threatened to simply kill any auditors. I am altogether unconvinced that the USG can have anything it wants for any price. Period. [↩]

Not disputing the numbers, but the conclusion does not follow. A weapon does not need to boil the earth to be effective. Consider an ordinary rifle bullet. Or, for that matter, poison.
Even think of conventional explosive - the energy in a hand-grenade is considerably less than what is contained in a coffee cup of petrol. To borrow the chemists' parlance, it is the -kinetics- rather than -thermodynamics- of the situation which matter here.
Humans also have a way of concentrating themselves conveniently for the kill, like the proverbial 'fish in a barrel.' - e.g., city, or column of tanks.
Hey, let's do the numbers after all! - 21MJoule ? A heavy anti-aircraft gun yields ~20KJoule on impact. And yes, I would rather take the 20KJoule from being pushed in a car for a hundred metres, than from a direct hit of an antiaircraft cannon, and the 21MJoule by sitting in the sun for a day rather than from a nuke. Why might this be ?

But the predicate of the effectuality of this particular weapon is specifically that it "would boil the earth". That is why the title reads as it reads - because to many people, nukes are a sort of magical, "will boil the earth" device. They aren't.
The point isn't that they are not useful at all - that'd be ridiculous. The point is that they aren't the magical "press this button to win any war" weapons fat lazy slobs wishing for a magical "press this button to solve any problems" are looking for and thus very likely to "find".
The comparison with the hand grenade and the discussion of kinetics vs thermodynamics is particularly weak. There is no frag nuke. It is a purely thermodynamic weapon, exactly like fuel bombs (which is what they technically are - different type of fuel, just as wasteful and primitive, as decimation well pointed out). It is altogether improbable that an advanced power in war will find such wastage to its advantage. Germany did not throw gasoline bombs at London for similar reasons.
Human concentration is a thing of Versailles, and thus of the past. That entire model of human civilisation is gone, with "popular democracy" and socialism. Sure, winning the wars of the past is the principal preoccupation of [inept] war planners. Nevertheless, it's neither sensible nor does it win wars.
Monday, 11 May 2015
The context where I mentioned the atomic weapon was this:
asciilifeform: when it was, instead, 'who has longest sovereignty cock' - folks willingly died for the glory of $empire, yes
and I don't see how the glory of $empire can be maintained if one or few largest centers or "holy shrines" of that civilization get turned into barren wasteland. Not even wasteland - few nukes can be creatively used to disable large part of nation's power transformers, or pipelines/oil refineries... can go on. The entire model of human civilization is not gone, instead its critical points are now elsewhere.
Monday, 11 May 2015
But the critical points of human civilisation have long been gone out of the physical land.
Think of it in practical terms : both Russia and the US know that China is too large to be effectually nuked, which knowledge quite visibly informs their policy towards it. Now if nukes actually worked... why would this be ?
Monday, 11 May 2015
Of course, if you boneheadedly insist that "effectually nuked" means "nobody survives"...
Monday, 11 May 2015
The only thing "effectually nuked" means is the very meta "spending a lot of time talking about it as if it were a thing". The bonehead move is to insist it actually means anything other than that.
Nukes are the first pop starlets.

I reproduce below a PDF that was originally published by cryptome and graciously de-stupidified (STOP USING PDF OMFG!) by alf.
I know of no better proof that the "atomic weapons not actually militarily useful" than this sort of perennial wank. If you don't know that the security surrounding these allegedly essential important weapons is at best a joke and at most something outsourced to Hollywood, if you don't know about the malfunctioning latrines, the missing tools, etc etc... well, that just says something about how informed you are.

Mr. Popescu: While I don't question your math with respect to uranium energy, aren't you failing to take into account that it takes relatively little fissile material in order to start a massive fusion reaction? Modern fusion warheads release 1000x the energy of their WWII predecessors. The amount of available fusible material may indeed be enough to "boil the seas".
Tuesday, 19 May 2015
It is true that the math presented discusses an obsolete approach, and it is true that modern weapons use fusion/fission sandwiching to achieve payloads grossly speaking three degrees of magnitude larger than what's contemplated here.
Whether this is sufficient to boil the seas or not in anyone's view is, of course, open to that one's own arbitration. Nevertheless, in pure energetic terms, three degrees of magnitude take the energy expenditure from "one afternoon's sunshine" to "three years' worth of sunshine delivered within seconds", or roughly speaking drying off meters' worth of water. This certainly seems to qualify.
On the other hand, as far as the issue of costs is concerned, this modernisation also significantly increases the costs involved. Perhaps not by three degrees of magnitude, but nevertheless significantly enough. You will remember the part that says
Delivery will still be required, irrespective of type of payload - and the ratings of these missiles is actually based on the modern process from what I can determine, so nothing seriously changes on this score.
In any case, the proposition here isn't that nuclear weapons don't exist, or don't work, or can't be had or can't be made to work. The proposition is that their principal utility lies in military marketing rather than military operations, and that the general public's apparent ignorance on the topic seems to have a lot to do with the propaganda needs therein incumbent. Similarly to how ownership (or drivership) of a red Firebird doesn't make one rich, or a good sexual fit, or an apt future parent - even if teenagers seem to have thought so at some time, in some place, somewhere, in a galaxy far, far away...

I see. He with the biggest missile has the bestest army. The soviets lit off tsar bomba, and the world cowered in fear all the way until the fall of the Berlin wall.
Tuesday, 19 May 2015
Well, if you're old enough you did spend some time in your youth cowering under benches. Amusing, huh ?

It's funny how the duck and cover campaigns are the subject of so much scorn. As if those guys from the 1950s were idiots. Really? Those "idiots" survived WWII, and they better understood war, bombs, and even nukes than anyone since. They knew that in the event of a nuclear attack, unless you're in the epicenter (unlikely), you aren't going to be vaporized, but neither do you want the kiddies running outside to stare at the pretty light.
Contrast that with the 1980s, where they were hanging up posters saying "Warning! In the event of a nuclear attack, follow these instructions: 1. Bend over. 2. Put your head between your legs. 3. Kiss your ass goodbye."
Proves your point, I suppose. Nukes are military marketing.
As are the Olympics...

In the golden age of the nuclear bomb, 1950s to 1990s, the mantra went "If you own you've won, but if you use you lose." That is exactly correct, and contrary to what was alleged in the propa-press throughout and hence, nobody was going to use them in retaliation of someone else having used them first. Why waste an excellent opportunity to take wholly hallucinated "higher moral ground" and deliver to the poor sod a thorough Nazi thrashing?
With the gradual demise of the colonial powers, all huddled together in the tiny roost of Europe like a colony of noisy birds and the rise of the large Eurasian land powers (Russia, China, the slowly aggregating Arab panstate) the value and importance of the nuclear bomb evaporated. It seemed like a big deal in 1950, regarded through European eyes and an understanding of conflict that was strictly Continental - the same type of error that led Hitler to his failed attempt at subduing England through bombardment without actually having enough bombs, that had led Napoleon to try and dominate Russia without actually having enough soldiers and so on. It never was a big deal universally, just like Europe was never the world, just like Urbi et Orbi was a figure of speech, not a literalism.
tl;dr The author is exactly correct. I would know.

@qes Speaking of kiddies - the Ukr children of Chernobyl had famously bathed in the hot water (ex-coolant) leaking out of the re-configured reactor. Because hey, hot water was such a rarity in the Soviet Union no ape could pass it by! So... yeah.
The Olympics were, originally, exactly created for the purpose of advertising the sort of male prowess that constructed war at the time (in the Greek period, war basically consisted of what throughout modernity has passed for a children's game - namely, form two lines, hold tight together, bash into the others' line), and through that ploy a peace mechanism, yes. It also created the fat, unfit Athens that was later easy prey for the Macedonians (under Alex's father), the Latins and generally speaking any unwashed horde worth the salt on its skin.
@Obbenheimer Word!

Re: Olympics - I was thinking along slightly more modern lines, i.e. "The Soviets win all the gold, therefore every soldier in the Red Army is Ivan Drago."
Wednesday, 20 May 2015
From what I recall the Soviets, like the Romanians, mostly won the slut medals. Floor, horse, stuff like that.
